Description
An irreversible deterioration that most often occurs in vegetable tanned leathers from the late 1800s to early 1900s. Red rot produces a powdery red surface accompanied by cracking, delamination and loss of strength. The deteriorated leather exhibits a low pH and low hydrothermal stability. It is thought to be due to nontannin plant residues. Red rot is accelerated by light, ultraviolet radiation, an acidic environment, and sulfur dioxide pollutants.
